Porting and polishing Chevy engine heads involves removing material from the intake and exhaust ports to improve airflow, which enhances engine performance. Start by disassembling the heads and using a die grinder or rotary tool with various attachments to carefully reshape the ports, focusing on smoothing out rough areas and optimizing the flow path. After achieving the desired port shape, polish the surfaces using finer grit attachments to reduce turbulence. Always ensure to maintain the integrity of the head and avoid removing too much material, which could negatively impact performance.
